* Compile messages and keyed documents to module v2eunhhu2026-09-251-1/+1
| | | | | | | | | | | | | | | | | | aup now emits Pure module v2 and adds keyed byte collections (state documents: bytes by key), message inputs by key with u32 and a trailing bytes field, on-message handlers, field access, name[key] reads and .bytes sizes, replace(a .. b, value), reply and require, all checked for number/bytes types with file:line:column diagnostics. The document editor and its size-bounded variant are rewritten in aup. make check runs them through pure-edit-module against pure-edit running the original editor.pure programs: 1,280 random show/edit/apply operations, including conflicts, limits, missing documents, budgets and invalid keys, produce byte-identical stdout, stderr and exit codes, and each CLI reads the other's store identically. v0a parity with the workbench engine, 33 diagnostics and generated/damaged programs still pass, also with a sanitizer-built compiler.
* Set the DSL direction and the text modeleunhhu2026-09-251-0/+70
aup declares connections and leaves storage, transactions and screen models to Pure. Interface vocabulary lives in Vega, an aup library, not in the language. text is one immutable UTF-8 type from a word to a 1 MiB document; positions are cursors bound to a value that stay on character boundaries and follow edits, lengths name their unit, and comparison is exact without silent normalization. Stages v0b-v0d and their acceptance tests are listed.
